ICD-10 Code H53.02 – Refractive amblyopia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H53.02 – Refractive amblyopia
What it is
Refractive amblyopia is reduced vision caused by unequal or significant uncorrected refractive error during visual development. It reflects decreased visual acuity that is not fully explained by eye disease alone.
Clinical signs
Typical findings include reduced best-corrected visual acuity in one or both eyes and a history of anisometropia or high uncorrected refractive error. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents amblyopia attributed to refractive error, such as anisometropic or isoametropic amblyopia. It fits pediatric or other developmental cases where vision loss is linked to refractive imbalance rather than structural eye disease.
Do not use for
Do not use it for visual loss from cataract, strabismus alone, or other ocular pathology unless refractive amblyopia is specifically documented. Check documentation.
Coding tip
Confirm that the provider links amblyopia to refractive error and not another cause before assigning H53.02.
